摘要
文章根据α-链对角占优矩阵与非奇H-矩阵的关系,通过构造迭代参数的方法,给出了判定非奇H-矩阵的一组含参数迭代判定条件,推广和改进了相关结果。数值算例说明了该判定方法的有效性。
In this paper ,by the method of constructing iterative coefficient ,some new iterative criteria with parameter for nonsingular H-matrices are given according to the relations between α-chain diago-nally dominant matrices and nonsingular H-matrices ,which extend and improve some related results . Effectiveness of these criteria is illustrated by numerical examples .
